It was with a domestic station about 400 km or 250 miles north of Tokyo.
My dipole antenna is for the 40m band with the length of about 10 m for each side, and it does not work well on the 80m band as it is.
Its radiation impedance is ZL=11.8 – 1061 [ohm] and the VSWR value is 1913 at 3.550MHz.
MMANA-GAL is an antenna-analyzing tool, but it can also tell you the network you need in such cases.
If you prefer to solve the problem with a Smith Chart, the following figures may help.
Since your antenna is short for the band and thus highly capacitive, you first need to add some inductor in series. But its inductance, XL=1082 [ohm], is slightly larger than to exactly compensate the imaginary part of ZL=11.8 – 1061 [ohm] to have XL+ZL not on the Im{Z}=0 line, which is the only straight line on the chart, but on the upper half of the yellow circle.
And then with C2=1613pF in parallel, you will have Zin=50.0 + j0.0 [ohm].
